I have a 1999 v70 T5, with 71,000 miles. I have had continual problems with check engine light being on. I've had it at the dealership many times this past wo years. They have fixed hoses, sensors, gaskets and o-rings. Today, after filling up the car with regular unleaded gas, I pulled in the drive ...

I've tried to ask more intelligent questions, thanks to this forum. This is what I was told. With the upgraded software, the MAF sensor can now better measure the amount of air flow. Because the MAF wasn't up to standard, I received a check engine light. Does this sound reasonable?

The service manager called this am. He was looking at my file and sees all the trouble occurred when I received the software upgrade. He wants to send someone up here (I live an 1 hr outside the city) give me a loaner and take my car back. They want to re-trace everything that has occurred since the...

Thanks for all the encouragement. Tomorrow, I'll call the dealer and try and get the other codes from them and cancel my Tues appointment. Then I'm calling North American headquarters and complain. Is there a good probability that once the MAF is fixed that the check engine light will come back on? ...

I'm back with the code. 1171. The autozone guy thought the code might be the MAF.

Do you think I should still call and complain about the software?

Thanks again.

Thanks so much. I'll purchase the OBD-11 device and call the 800 #. You've given me the confidence to move forward. I'll let you know the outcomes. I may have most of this resolved by Monday eve.

I'll be back.

Thanks. You are so right. I'll head to the auto today and purchase one. But, I woke up in the middle of the night and I remember exactly when it happened. This may be something. I received a recall notice to take the car in for servicing. (This was a reminder notice because I forgot about the 1st on...

Thanks so much for responding. The car has also 68,000 miles on it and is a T5. The check engine light is on. I took it to an auto repair place (repairs only Volvos) and they couldn't fix it because they said they didn't have the codes. They implied these codes were secret that only dealers have the...

My CEL comes on and I've had a gasket and fresh air hose replaced ($800 so far). Now the dealer wants to replace the MAF. I've read the posts and think maybe I (widow - female) might be able to at least clean and or replace it myself. I know absolutely nothing about cars except the dealer charges wa...
